"to keep our country free from all atrocities" - that just a fantasy version of American history. There proabbaly aren't any countries, definitely no big countries which have a history "free from all atrocities", and the USA is definitely not an exception to that.

The general opinion of Christians round the world is that regard pride iss a sin, and humility is a virtue. If there's a version of "Christianity" that sees it the other way round it ought maybe to call itself something else.
